Then I shall let scripture interpret scripture.
God tells us to repent (an 'ought to' statement meaning that I either can choose to repent, or choose not to repent) Luke 13:3. If it was a sovereign command as opposed to a moral command, then all would have to repent, as God is sovereign and all His commands will be obeyed. However, if it is part of His moral will, then we have a choice. Free will is not doing whatever one wants or desires, but doing what one chooses. I choose to do something which I could have chosen to do otherwise.
We given a choice to believe (John 3:16, 3:36, Acts 16:31).
God does not wish any should perish (2 peter 3:9). If this was sovereign will, then you would have to hold to universalism.
We believers should abstain from sexual immorality (1 Thes 4:3-8). Do all believers abstain from sexual immorality (or any sin for that matter)?
It is God's will that we should be in subjection to all authority (1 Peter 2:13-15) yet Christians still break the speed limit, run stop signs, cheat on their taxes, etc.
You can look at the 10 commandments. God, by His will, gave the commandments, yet we break them all of the time. (Hence the need for a Savior).
It does seem that God gives us choices, and gives commands that we do not follow by our own free choice. We can choose to lie, or not lie. We can choose to steal, or not steal. We can choose to break the speed limit, or not break the speed limit. If these things were determined by God, there would be no need for rewards or punishment, since we were only doing what we were compelled to do.
Well, I guess that is enough for now. Still wanting to know, though, if I should change my view on determinism.
